Abstract: Wireless Ad Hoc Networks (MANETs) can to provide first responders and disaster management agencies with a reliable communication network in the event of a large-scale natural disaster that devastates majority of the existing communication infrastructure. Without requiring a fixed infrastructure, MANETs can be quickly deployed after a large-scale natural disaster or a terrorist attack. On the other hand, MANETs have dynamic topologies which could be disconnected because of the mobility of nodes. This paper presents a decentralized approach to maintain the connectivity of a MANET using autonomous, intelligent agents. Concepts from the social network analysis along with flocking algorithms are utilized to guide the deployment decision of agents. Unlike a basic flocking algorithm where all nodes have the same importance, network metrics are used to quantify the relative importance of nodes. Computational results are presented to demonstrate the effect of various local agent behaviors on the global network connectivity.

Abstract: This paper describes an ongoing project that exploits the capability of mobile sharing systems for ad-hoc wireless networks (MANET) operating in a post-emergency scenario. The aim is to support an existing adaptive process management in which users handle multimedia files (e.g. disaster photos) in a nomadic way by exploiting the capability offered by mobile file sharing middleware to reduce the connection time for each nomadic operator performing emergency workflow. The paper compares user activities with and without file sharing capability in order to show the efficiency gain that could be obtained. A preliminary discussion with example of activity diagrams evidences the benefits in terms of workflow efficiency and gives the opportunity in the software project development phase to obtain a more scalable and efficiently performing mobile adaptive process management for crisis scenarios.

Abstract: In this paper we describe a disaster management system. It is assumed that each individual in the field is equipped with a PDA (Personal Digital Assistant) and that can communicate with other PDAs in the vicinity. Together the PDAs form an ad-hoc network. Users can enter their own observations to the PDA, like the position of victims, or a description of the current situation at particular location (e.g. smoke, emergency exits, traffic congestion). This information is entered in a special iconic language. Reversibly, the PDAs inform the users on the overall current situation of the crisis. In order to come to a shared view of the world, the knowledge that is present in the network has to be shared and fused. The proposed way to communicate is via a shared blackboard. This approach facilitates communication in a time and place independent way.
